Hello, I have two different projects in parallel right now, both of which use STM32G0B1 MCUs. On both projects, with completely seperate hardware, the VREFpin that connects to the internal VREFBUF peripheral is innacurate. These pins are just brought...
Hey all, I'm trying to generate DMA PWM for a row of 3 Neopixels. I succeeded on a Nucleo-based L496, but translating to a L4P5 target (custom board) results in no output on the GPIO at all. I've compared the generated HAL code for both and cannot fi...
Started a project based on the STM32L010 which needs to receive six bytes from the UART. Works fine if I use it in interrupt mode. Does NOT work if I use it in DMA mode. Saw multiple posts about the DMA needing to be init'd before the peripheral in q...
Hi there,I have a STM32L431RCT6 microcontroller. I wish to write some data on it. let's say I want to write 2 at 0x08009000 Address.here is my code#define FLASH_USER_START_ADDR ((uint32_t)0x08009000) #define FLASH_USER_END_ADDR ((u...
We have facing issue on microntroller we have recieve we have serial product and curretly we are using STM32F072VBT6 controller but we have order new lot and we are recieve STM32F072VBT6 2 and both are behaviour diffrent so what is major diffrence be...
When we test adc small signals, we found all spi have impact on adc1 and adc2 module, which leads unexpect singals even we use fund HDs of it.Detals as below:--Environment:Save 6400 points at different conditions,1. spi2 or spi4 work and really has i...
i have used the board nucleo stm32h745 Board.i have used can 1 and can2 for data exchange but my data is also showing with some simple text ,screenshort is attached. i am sending voltage text at can1 and hello at can2,and but i am getting some text w...
Using Tim3 with 84MHz clock, and need an 192 KHz trigger, for 96 KHz the prescaler is 875-1, clearly half that is a fraction, the calculators mentioned on line no longer work, is there a solution?
i can not get full text msg ,some alphabats are missing each time .how i can solve this ?
