STM32 communication with a display via I2C over DMA
Hi Everyone,My problem relates to I2C communication when trying to send bytes to a display on address 0x78. First I tried with the plain I2C HAL function(blocking), but I realised that the MCU gets frozen because of the huge amount of data to be sent...
Stm32F407 Clock Configuration Issue
Hi, I am working on my Stm32F407 Discovery Board. I use CMSIS when I codding and I have some problems with PLLCFGR register. I want to using 168 mhz clock speed. This is my Clock Configuration code and I get problem in PLLM configuration in PLLCFGR r...
STM32H7 I2C DMA ll, just sending once
Hey guys, I am trying to get I2C working with DMA or without, but I am having similar issues with both. The I2C sends out the data correctly the first time via DMA and the DMA_TC interrupt is called, however it gets never called again. I can also see...
Resolved! Blinky not working - possibly incomplete pin configuration?
Hello,I was following the step by step guide by st for an easy led blink program. And after configurating the pins in the GPIO_Init function the LEDs are not turning on. Is there something wrong in my code? Did I miss part of the pin configuration? A...
STM32 Major LPTIMER documentation shortcoming or is it a silicon design error???
In looking at various LPTIM training documentation it's indicated very clearly that the LPTIMERs have a CNT reset as a function of setting bit 4 of the CR register. As this is an important capability, there seems to be a number of reference document...
Resolved! Weird timer behavior right after reset on STM32G4 - Inconsistent timebase
I'm using a timer as a 1ms timebase, which is configured right after hitting main, so very early. I use this timebase to implement timeout functionality in my drivers as I prefer to not just use while loops when waiting for something to complete.What...
STM32G4 ADC jitter from timer to conversion start.
Hi,What is the jitter value in nS when the ADC is configured for Asynchronous clock mode? consider CPU clock = 170MHZ, adc_hclk = 170MHZ, adc_ker_ck = 170/6 MHZ = 56.67MHZ and ADC clock = 56.67MHZ (PRESC = 0)ST inform in the manual that the jitter i...
