Hello everyone, I am trying to measure how much time is used to finish executing a function. I cannot use the timers because it adds some delay to the system. My other option is to use GPIO pins.To do this, ISET a pin at the start of the functionRESE...
I'm using the HAL_I2C_Master_Transmit_DMA driver on an STM32L412. I am transmitting 8 bytes of data to an external 4 channel I2C DAC - I have only one device on the bus. The first use of the driver works fine as confirmed by using an oscilloscope on ...
Hello ST community,I have QSPI flash and an environment sensor based on SPI with stm32l496rg development board.If I put controller in stop mode 2 without sensor and flash current consumption of system is 3uA.If I connect flash and sensor then in stop...

Hello community,I have a problem with using usart6, although usart1 is working fine.My setup: STM32F439, usarts connected to a dual ftdi chip, so I have two com ports on the pc to choose of, which represent usart 1 on usart 6 resp.Also direct usb con...
please review the datasheet,--4 Pinouts and pin descriptions-- from the datasheet, both PIN 42/43 and 45/46 could be I2C1; both PIN 21/22 and 35/36 could be I2C2; which is right exactly?
Hello,I am measuring execution time of a function that operates with floating point numbers and noticed that it is more than I expect. I am using Nucleo F429ZI, clock is configured to the 50 MHz. For measuring the execution time I use TIM6 configured...
Are there pictures of microarchitectures of STM32F4 series devices? Something like this picture of 56301 DSP.http://strategysanity.com/s-images/dieDSP-Motorola56301.JPGWe'd like to find out what killed some processors on our boards. The dead processo...
Hi! I'm working in a bypass analog signal to external DAC and I did this isolating and checking (if H or L) each bit from adc buffer to load each 12 GPIOs. I'm looking for other soluton to do this. Can someone suggest other solution?
