Using an STM32H750 part, I've lived with the slack tolerance of the HSI until coming to the UART where a speed of 9000 bps is experienced from a configured 9600 bps. This is too far out to be of any use at all and therefore have decided to put on an ...
Hi!I'm using EA W162-XBLG OLED in SPI mode. Timing shown in datasheet is really weird. In instruction diagram there is 20 clock cycles, in data transmission 18. I try to get it to work with STM32F407VG, but I can only set 8 or 16 clock cycles. Maybe ...
I tried the STM32Cube Programmer but it could not connect to the board. I'm on Linux Manjaro. Many thanks
In dual ADC mode, the bit DMAEN is invalid as the doc said but in the below screenshot it is describing that the DMACFG bit in ADCx_CCR is effective only when DMAEN = 1.Please see the below snippets from the document. Need help from you whether I am...
We can read the data from ADCx_CDR register in dual mode. The upper half word of ADCx_CDR consists of slave data and the lower half word of ADCx_CDR consists of master data. But in the manual mentioned ADCx_CCR for master data and EOC cleared when we...
I have an STM32F7 Discovery card and I would like to know how to read a Wave sound backwards (reverse playback) via SAI and I2S interfaces ?I can play a Wave sound forward and change its speed with the library and documentation provided by ST.Thank y...
Hello,I am using the Nucleo-h745zi-q board.I want to know that is this board supports the nano framework?how can I get nanobooter and nanoclr files.Please guide as soon as possible.Thanks
I wanted to send looped signal pattern to I2C DAC at 1 MBit/s (around 100kHz sampling rate) and eventually found a solution. Original problem description: Because DAC is accepting 16bit frames I set NBYTES to 254 (254/2=127 DAC samples) and RELOAD bi...
i want to measure the time an interrupt handler costs.1. set a specified pin low at the beginning of the interrupt handler and high at the end of the interrupt handler like this:void EXTI4_IRQHandler(void) { /* USER CODE BEGIN EXTI4_IRQn 0 */ HAL...
Hi All,I'm using stm32f1 series. & truestudio.I want to set the PWM pin "High" when pwm does't starting pwm.But when i initialize the pwm, pwm pin is "Low".How can i set the pwm pin "high" when initializing.
