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...
I am trying to get LM35 temperature sensor value using STM32F411RE. When supply voltage fed to LM35 is 3.3 V, the correct digital data is produced. But when 5V is fed as supply to LM35, the digital values produced are the same as those when 3.3V is s...
