How to synchonize 2 PWM on the same clock.

Parsing GPS Messages ???

Dear Member, I want to parse GGA,GSV,ZDA,VTG,RMC,GLL,is my container not enough ?Sometimes I can parse it sometimes I miss......?line_buffer[2048];uint8_t      rxBuffer[768];      str=strstr((char*)GPS.rxBuffer,"$GPGSV,");            ProcessNMEALine(...

The address of the variable is the same

i using FreeRTOS.MB_Coil_Counter is a global variables and tmp is a variable in interrupt function of uart!why the address of tmp matches the address of MB!thank everyone

Hou to move the interruption vector table and make STM32F407VE work 32KB ahead.

I need 32KB of flash memory space to store data. As the smaller memory blocks are in the beginning, it sounded logical to use the first two blocks and move everything else 32KB forward.To achieve that I first edited the file STM32F407VE_FLASH.ld to c...

STM CUBE IEEE 1588-PTP drivers

Posted on May 07, 2018 at 20:15I cannot find PTP drivers in the CUBE software package. We have in house PTP stack developed which needs PTP driver interface. Does STM provide drivers for Ethernt PTP-module? It would be even great if STM can provide ...

PUTCHAR_PROTOTYPE question ?

Dear Members,Is it possible that I use two UART with  PUTCHAR_PROTOTYPE ?I have used UART3 with  PUTCHAR_PROTOTYPE for talking with PC,I want to use it as well for talking with modem (UART1)Thanks

SB bit of DMA2D_OPFCCR register missing on STM32H7?

Dear Sir/Madam,It seems that DMA2D_OPFCCR register SB bit described in the reference manual of the the STM32H7 (RM0433, page 721) is not implemented. Code generated by CubeMX is missing the definition completely, an attempt to set the bit directly fr...

I have an ic MCP3428, I'm trying to connect it by I2C. Now problem is that I'm writing a code to figure out what the exact I2C address is? but it doesn't work

for(uint8_t i=0;i<255;i++) { HAL_Delay(10); if(HAL_I2C_IsDeviceReady(&hi2c1,i,2,20)==HAL_OK) { uint8_t address=i; break; } }
