SMBUS Block write -Block read process with Middleware
Dear expertI am currently implementing the SMBUS communication with TI BQ40Z80 via STM32L431xxx + Middle ware.However, when observing the smbus waveform, N byte block write does not work properly and block read is also strange.Other register accesses...
STM32H753XI LWIP + MDMA
Hello, we're using STM32H753XI in our custom board wherein we've ADIN1200 LAN driver, W25Q flash on QUADSPI. we've configured the memory regions for Ethernet Rx, TX DMAs and pool memory like this RW_DMARxDscrTab 0x30040000 0x60 { *(.RxDecrip...
Issue with reading i2c eeprom memory with Nucleo-F446
Hello all . I have been working for days to make nucleo f446re reads i2c eeprom . The i2c eeprom am trying to read uses 0x78 address as the slave address . I tried use the Nucleo-64 f446re with stm32 cube ide using IsDeviceReady in hal i2c . And i...
Resolved! SPI communication with 3 wire display
Hi community,I have a display, which has only CLK, DI and CS pin for SPI communication. It uses TI protocol.The original driver is only working with raspberry pi, I try to import it into my custom STM32 MCU board, the CLK and CS signals seem okay, O...
Resolved! Writing data to STM32G4 Flash
Sorry, my first time programming an STM32. I have a bunch of data I need to store for a few hours, and the thought was to store it in Flash since there's a lot more of it (512k vs. 128k for regular RAM) but it looks to be pretty daunting. I've been ...
Resolved! STM32H723ZGT6 will not reboot after powering off
Hello All,I designed and built a bare metal board with an STM32H723ZGT6 and it runs fine.I have blinking LED's, timer / interrupts running, HSE and LSE etc.I have been trying to figure out why if I toggle the power supply the device will not boot up ...
STM32F756VGH6 register based interrupt syntax.
Hi,I am a beginner in STM32 programming. I chose purely register based programming approach without using HAL as I find it a bit harder and slower but more contributing to the overall system performance in the long term code writing skills. This time...
Resolved! UART data receive acknowledgement
Two devices A & B are communicating on UART. A sends data stream to B. B sends one byte data back to A to acknowldge that data has been received. I want to implement if A doesn't receive acknowledgement from B then it display Error message on LCD.Ple...
stm32l072rz higher stop mode current then stm32l072rb
Hello,we have a validated project based on the stm32l072rb (FLASH 128KB) microcontroller and in stop mode the entire system consumes 3.5uA.We have updated to the stm32l072rz (FLASH 192KB) and the stop mode current raised to 23uA. In standby mode both...
