Hello ,With SPI (SPI2 in my case) I experience a delay between a wite to TXDR and the start of the SCK activity in case of an empty TX fifo. It seems to be something like 5 SCK periods, so it changes with SCK frequency but this ratio remains. I check...
I configured the SPI2 port for bidirectional (BIDIMODE = 1) and rx (BIDIOE = 0), then enabled the port (SPE = 1). According to the RM the enable should immediately start sending clock pulses out the SCK pin and read data on the MOSI pin, since it is...
I have a LSE with a freq of 32.768KHz. The cube generated code uses values for AsynchPrediv = 127;SynchPrediv = 255;These values give around ~4ms resolution. Is it possible to get to ~1ms resolution?Thanks
We are working custom board which has stm32f103vct6 (LQPF 100pin) on it. Our aim is to interface flash memory with microcontroller through SPI1 module but mistakenly board designed as PC4 pin for chip select instead of PA4 pin. Is there any other...
I run my CPU mostly (when possible) in stop2 mode. I want EXTI interrupt from few pins to wake it up. What i found is that sometimes it doesn't. ...
Good morning,We're using an STM32H7 to acquire simoultaneously 3 ADC channels 16-bit @ 5MSPS, and we store data in an external eMMC. Everything worth seamlessly as follow : 3 slave-SPI with 3 DMA to internal flip/flop buffers ; MDMA to interleave dat...
Posted on March 21, 2015 at 15:09I am newbie to stm32. On nucleo401 board i want to use six analog inputs together. ST suggest that we should use stm32cube (HAL) instead of Standard Peripheral Library. But i can't find the example of multichannel ad...
Hello everyone.İ am a new member.For several years i have been writing codes in pic ucontrollers as hobbiest. İ write codes in MPLAB X and CCS C for pic ucontrollers especially in 8 bit ones .But i want to turn my hobies into a job. When i see the jo...
Dear guys.i have a problem.I used the STM32F103VCT.I control 3 color RGB LED using TIM1 PWM CH1~3 and i set the pwm parameter by CubeMX.After set the pwm, the pwm function is good work, but other device - USART1 is not work and debug mode is automati...
In the STM32L4 Nucleo examples, all GPIO on the processor are configured for analog mode before entering stop1 or stop2 modes. In a typical application, there will be some lines that must remain either high or low as to not turn on any external circu...
