Hello, I have a custom designed board with 7 analog inputs on sigma delta ADC's.6 of my inputs are working properly. I have a software issue.When I erase the flash or de-solder the mcu I can measure the correct voltage from my test points.But when I ...
I'm stock since a while now.I use H723 nucleo board with a SD card socket, build for SPI, but I use it as SDMMC with 1bit wide.this socket is ok with SD and SPI.f_mount send FR_NOT_READY.I have the same answer with or with out Sd card...I use a logic...
1. Hardware requirement I/O - Minimum 12 SPI, I2C, UART, WDT, ADC2. MEMORY NEEDS MINI 32K FLASH & 4K RAM3. Ultra low power & Power Mode power down current < 1 uA I/O Pin to retain it's state Package :- LQFPFree software libraries and exa...
We have been experiencing dropped bytes during UART communications and have determined the root cause to be an unstable external oscillator. The external oscillator placement does not follow the recommended guidelines and is resulting in the PLL desy...
Hey Guys,I am working with the STM32L476RG Nucleo board (however my custom board has the L462 chip - I am hoping the solution will work for both chips) and I am trying to get multiple channels ADC interrupts to work without success. My CubeMX setup i...
I have a custom board with stm32L496ZG similar to stm32L496G-disco evaluation board.only the CLK and CS for quad spi are different. I want to use the programmer to check the functionality of the external flash that is connected with quad spi. I have ...
Hi,I'm currently using HRTIM on a STM32G474RE and I'm facing a configuration problem.Context :The HRTIM is used to produce 2 push-pull PWM outputs from Timer A. The 2 outputs are configured the same way :1 Set source : Timer period event2 Reset sourc...
Hi there,I have 2 modebus register 0x0010, 0x0011. These are enable encryptionkey value. There square vaule should be less then 255 for some reason. This modebus register can be allowed for certain command functions as follows.void ModebusSetCMD_ENE...
I'm sure ST must have a better idea than we do. Distributors seem to be saying "not in the foreseeable future", which I take to mean at least the end of 2023. Obviously no-one has a crystal ball, but a guess would be better than nothing. It does...
Could someone tell me, what I'm doing wrong? Why can't I find out the memory value in "Memory browser" window?Very simple code: uint8_t p = HAL_GPIO_ReadPin(LED_GPIO_Port, LED_Pin); printf("Address of variable 'p' is: %p\r\n", &p); // 0x20004ff7
