STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello,I need to sample an ADC at 20ms using SPI. I setup a timer interrupt to do this, but I would like to fill a double buffer at SPI_RxHalfCplt and RXCplt.My timer seems to be working correctly, however the Rx Half Complete Callback is being Called...
I keep the important information in 32 byte. But every block have 32 byte .There are more than 300 block and every block have 32 bytes of data. So I've 32*300 byte data. How can I keep in the RAM successfully. Sould I Keep with array (uint32_t) or po...
I'm using STM32F105RBT, and I'm finding that, in certain circumstances, the phase locked loop is failing to become ready.1) Boot (sysclk = HSI @8MHz)2) Set PLL with source=HSI(div2) and multiplier=93) Enable PLL4) Wait for PLL ready (waits forever he...
Based on the sample software of FMC_NOR, I am creating a program to store the data received by UART in NOR memory.Operation content:(1) Data reception via UART(2) Write the received data to NOR memory(3) Use the reset switch to switch to the receptio...
Hello, i am trying to communicate with an MRAM memory (Micron) via octoSPI but i can't manage to make it work! i already looked at the ST code examples and i got the same configuration as the examples but it just doesn't work. Please help!PS: i am us...
Hi, I had a weird issue with an STM32F334 MCU. A pin was configured as Open Drain - this pin is used for falling edge interrupt and pulled up by a different section of the design. But I had issue today with the operation of the pin and realised the M...
Hi,I'm trying to use STM32F407 to develop bluetooth audio device. I use the cc2564c bluetooth board and CC256XEM-STADAPT board made by Texas Instruments. Now I need to use UART2 to connect the STM32 board with PC, but the PA2 and PA3 pins are used b...
Hello, I'm using the demoboard (B_U585I_IOT02A) in order to read an analogic input (between 1V and 2V for my tests) and I'm currently trying to use the ADC. I say "trying" because, for now, I still haven't been able to read the values correctly. Fo...
We are using I2C channel 1 for EEPROM and RTC (Semophore used for exclusive access) and I2C channel 2 for Touch controller. Both I2C runs at 400KHz. Everything works normally, Suddenly I2C channel 1 becomes busy at random time. It is really hard to r...
