UART Kev Sib Tham Txheej Txheem

UART yog hom kev sib txuas lus sib txuas ntawm qhov sib txuas uas siv cov ntaub ntawv sib txuas-rau-serial hloov dua siab tshiab ntawm nws lub transmitter thiab tom qab ntawd sib txuas lus nrog tus txais zoo sib xws. Lub receiver ces ua ib tug serial-rau-parallel cov ntaub ntawv hloov dua siab tshiab tom qab cov ntaub ntawv txais. Daim duab 1 qhia ib daim duab schematic ntawm serial kev sib txuas lus qhia yuav ua li cas cov ntaub ntawv raug xa mus rau hauv ib qho kev txiav txim me ntsis. Yog li ntawd, rau kev sib txuas lus bidirectional ntawm transmitter thiab receiver, tsuas yog ob lub xov hlau, TX thiab RX, yuav tsum tau hloov cov ntaub ntawv serially ntawm ib leeg. TX yog tus pin uas UART xa cov ntaub ntawv serial thiab txuas nrog RX tus pin ntawm tus txais. Yog li ntawd, lub transmitter thiab receiver pab kiag li lawm yuav tsum tau hla-txuas lawv TX thiab RX pins ua UART ob-txoj kev sib txuas lus, raws li qhia nyob rau hauv Daim duab 2.

Thaum lub sij hawm UART serial kev sib txuas lus, cov ntaub ntawv kis tau tus mob yog asynchronous. Qhov no txhais tau hais tias tsis muaj moos lossis lwm yam teeb liab synchronization ntawm lub transmitter thiab receiver. Ntawm no yog baud tus nqi yog siv, uas yog cov ntaub ntawv serial kis / tau txais ceev thiab uas yog teem los ntawm ob sab ua ntej ntawm cov ntaub ntawv hloov lwm lub tsev. Tsis tas li ntawd, cov khoom tshwj xeeb xws li pib thiab nres cov khoom raug ntxiv rau qhov pib thiab qhov kawg ntawm cov ntaub ntawv pob ntawv los tsim ib daim ntawv UART cov ntaub ntawv tiav. Daim duab 3 qhia UART cov ntaub ntawv pob ntawv qauv thaum daim duab 4 qhia UART 8-ntsis cov ntaub ntawv pob ntawv yam tsis muaj qhov sib npaug me ntsis.

Daim duab 4. UART 8-ntsis Data Packet Format

Txhua feem ntawm UART cov ntaub ntawv pob tau qhia nyob rau hauv kev txiav txim hauv qab no.

• Pib ntsis: Qhov no qhia txog qhov pib ntawm pob ntawv cov ntaub ntawv. UART TX tus pin feem ntau tseem nyob rau theem siab logic ua ntej kev sib kis pib. Yog tias cov ntaub ntawv xa tawm pib, UART transmitter yuav rub TX tus pin los ntawm siab mus rau qis, piv txwv li, los ntawm 1 txog 0, thiab tom qab ntawd tuav nws rau ib lub voj voog. Tus neeg txais UART yuav pib nyeem cov ntaub ntawv thaum qhov kev hloov pauv siab mus rau qis tau kuaj pom ntawm RX tus pin.
• Cov ntaub ntawv: Qhov no yog qhov tseeb cov ntaub ntawv xa mus, nrog cov ntaub ntawv ntev ntawm 7, 8 lossis 9 ntsis. Cov ntaub ntawv feem ntau yog pauv nrog LSB ua ntej.
• Parity ntsis: Tus naj npawb ntawm cov logic "1" hauv cov ntaub ntawv yog siv los txiav txim seb puas muaj cov ntaub ntawv hloov pauv thaum lub sijhawm xa mus. Rau qhov sib luag, tag nrho cov logic "1" hauv cov ntaub ntawv yuav tsum yog tus lej sib npaug, qhov sib txawv, tag nrho cov logic "1" hauv cov ntaub ntawv yuav tsum yog tus lej khib rau khib parity.
• Nres Nres: Qhov no qhia txog qhov kawg ntawm pob ntawv cov ntaub ntawv, qhov twg UART transmitter yuav rub TX tus pin los ntawm qis mus rau siab, piv txwv li, los ntawm 0 mus rau 1, thiab tom qab ntawd tuav nws nyob ntawd rau 1 lossis 2-ntsis lub sijhawm.

Raws li tau hais ua ntej, txij li tsis muaj lub moos teeb liab hauv UART Circuit Court, tib cov ntaub ntawv serial kis / tau txais ceev, uas yog hu ua baud tus nqi, yuav tsum tau txhais ntawm lub transmitter thiab receiver los ua qhov yuam kev tsis pub kis. Tus nqi baud yog txhais los ntawm tus naj npawb ntawm cov khoom xa mus ib ob, hauv bps (ntsis ib thib ob). Qee tus qauv thiab feem ntau siv baud tus nqi yog 4800bps, 9600bps, 19200bps, 115200bps, thiab lwm yam. Lub sijhawm sib thooj uas xav tau rau kev xa cov ntaub ntawv me ntsis yog qhia hauv qab no.

Nco tseg: 

1. Hauv "UART_Module_Example” daim ntawv thov code, API nyeem thiab sau cov haujlwm tau ua nyob rau hauv lub voj voog rov qab, xa mus rau “API Siv Examples” seem kom paub meej ntxiv.
2.  Hauv "UART_Bridge" daim ntawv thov code, ob lub UART channels, UART CH0 thiab UART CH1, tau qhib, thiab kev cai sib txuas lus raws tu qauv los ntawm cov qauv COMMAND yog siv los ntawm ob lub UART li. Yog xav paub ntxiv, xa mus rau "API Siv Examples” section.
3. Daim ntawv thov code yuav tsum siv uart_module.c/h files uas muaj firmware tsev qiv ntawv version yuav tsum tau. Qhov kev xav tau tuaj yeem hloov pauv sijhawm raws li qhov hloov tshiab. Txhawm rau kom paub meej tias qhov xav tau ntawm cov tsev qiv ntawv firmware tam sim no, xa mus rau qhov kev txheeb xyuas cov ntsiab lus los ntawm kev tshawb nrhiav lo lus tseem ceeb "Dependency check" hauv main.c file. Yog tias lub tsev qiv ntawv firmware tsis ua raws li qhov yuav tsum tau ua, rub tawm cov ntawv tshiab tshaj plaws los ntawm qhov txuas tau muab rau hauv "Firmware Library" ntu.

API Architecture
Txhua API muaj ib qho tseem ceeb parameter CH, uas yog UART Channel. Qhov no txiav txim siab uas UART channel yuav tsum tau tswj. Tam sim no txog li plaub UART channel tau txais kev txhawb nqa thiab yog li plaub lub cim tas li raug txhais raws li hauv qab no. Cov no yog siv los ua qhov parameter CH muab cov APIs hauv paus rau kev tswj hwm.

• UARTM_CH0: input parameter - tswj lossis teeb tsa UART CH0
• UARTM_CH1: input parameter - tswj lossis teeb tsa UART CH1
• UARTM_CH2: input parameter - tswj lossis teeb tsa UART CH2
• UARTM_CH3: input parameter - tswj lossis teeb tsa UART CH3

Qhov chaw nco yuav tsis raug pov tseg yog tias tsuas yog siv UART channel xwb. Qhov no yog vim hais tias tus naj npawb ntawm UART channels txhawb nqa tuaj yeem teeb tsa thiab tsis siv UART channel code yuav raug tshem tawm los ntawm tus txheej txheem ua ntej kom nce qhov chaw nco. API architecture qhia hauv Daim duab 9.

Daim duab 9. API Architecture Block Diagram

Txhua API yog tsim los ntawm plaub pawg ntawm UART channel-txog kev teeb tsa lossis kev tswj hwm kom cov neeg siv tsuas yog xav tau nkag mus rau qhov xav tau CH parameter. Txhawm rau txhim kho qhov cuam tshuam API, nws tsuas yog yuav tsum muaj UART cov lus qhia kev teeb tsa yooj yim nrog cov qauv qauv, USART_InitTypeDef. API yuav siv UART qhov kev teeb tsa yooj yim raws li cov ntsiab lus parameter hauv cov lus. Xa mus rau ntu "API Description" rau UART cov lus qhia kev teeb tsa yooj yim.

Uart_module.c/.h files tsuas yog muaj qhov cuam tshuam (CHx_IRQ) ​​thiab cov lus teev xwm txheej (CHx Status) ntawm txhua qhov UART channel thaum tag nrho cov chaw xav tau rau UART kev sib txuas lus yog muab los ntawm ht32_board_config.h. Cov cuab yeej muaj feem cuam tshuam rau hauv ht32_board_config.h file muaj nyob rau hauv cov lus hauv qab no. Cov ntsiab lus ntxiv muaj nyob rau hauv seem "Setting Description".

Cov kev kho vajtse muaj feem cuam tshuam hauv ht32_board_config.h suav nrog I/O chaw thiab UART chaw nres nkoj lub cev, raws li hauv qab no.

Table 3. Txhais cov cim hauv ht32_board_config.h

Txhawm rau hloov kho UART channel AFIO teeb tsa, xa mus rau cov ntaub ntawv cov cuab yeej cuam tshuam. Tam sim no tsuas yog I/O cov lus txhais rau UART CH0 nkaus xwb raws li tsuas yog UART CH0 tau teeb tsa hauv ht32_board_config.h. Txhawm rau ntxiv UART CH1 ~ 3, lawv cov lus txhais I / O yuav tsum ua kom tiav los ntawm kev xa mus rau UART CH0 txhais lossis xa mus rau "Setting Modification and FAQs" section.

Muaj peb yam API architecture tseem ceeb: 

1. Txog li plaub UART channel tau txais kev txhawb nqa. Lawv input parameters yog UARTM_CH0, UARTM_CH1, UARTM_CH2 thiab UARTM_CH3.
2.  Tus naj npawb ntawm UART channel tuaj yeem teeb tsa thiab cov channel tsis siv yuav tsis txo qhov chaw nco.
3. Txhua qhov UART teeb tsa thiab I / O txhais tau raug cais tawm ntawm APIs. Qhov no ua rau kom muaj kev tswj xyuas yooj yim ntawm kev teeb tsa qhov tseem ceeb thiab txo qhov muaj peev xwm ntawm qhov tsis raug lossis ploj lawm.

Kev piav qhia 

Tshooj lus no yuav qhia txog qhov teeb tsa parameter hauv ht32_board_config.h thiab uart_module.h files.
