I have a Cypress S25FL064 flash memory connected through QSPI interface to a STM32H753.The memory is booting in "single IO" mode (ie. classical SPI protocol with MISO/MOSI signals).In this mode I am able to erase, program and read the memory through ...
Hi everybody,I am using STM32G070KB and trying to generate a LIN break. But this seems to be only 10 bits long instead of the described 13 bits. If I am right the break should be about 680µs long at 19.2kBaud. But it is only about 520µs long which is...
All health!I tried to connect the display on ILI9341 to STM32G474VET6 using FMC. There were no problems with stones F1, F3, F4, F7. And with G4, an interesting plug is obtained - for each byte, a 0x00 byte is added. I read Eratu - there is nothing. I...
What should be the minimum pulse width of the signal which can be detected by the GPIO pin of the STM32 and on which factor this detection depends upon?
VREFBUFF is not available in STM32L431RCTx series, in datasheet it tells that "internal voltage reference buffer is not available", is there any other option to give External ADC reference for this series of STM32.
I need to generate PWM on a non-PWM pinI know one method is to use an ISR triggered by a timer, but because I need to run the PWM at 10kHz, this will put a huge load on the CPU just to toggle 1 pin.I've seen examples of using DMA to send data to the ...
we are reading pH sensor by using nucleo 32L746RG.even though both VDD and sensor value looks stable on tester like 3.3v+-0.1mv/ 2v+- 1mv, the adc value shows about 10% up/down around the true value.the adc value seems to repeat increasing and decre...
As titled, with little definition, how do I configure the NVIC_Type struct ? Directly use the numbers that are difficult to maintain later? Or in fact they have official definitions, but they were hidden somewhere else ?And another question, where ca...
I use the UART RX DMA mode to receive the data from the peripheral. This peripheral could endless send the data after powering up. However after serval rounds UART IRQ handler execution, the UART port couldn’t enter the IRQ handler anymore while the...
I Want to use the TIM2 with two channels in "Input capture mode". CH1--> PA0CH2-->PA1 Now I have two trigger pulses which I will connect to PA0 and PA1, Signal at PA0 will start the TIM2 and signal at PA1 will stop the TIM2.So how I can get the count...
