I2C commands to LCD

I am learning this new 32-bit from my 8-bit world as well as new IDE on top of re-learning C. So be gentle....I am trying to use the CubeIDE to talk to an I2C LCD. I am following a tutorial but the LCD does not respond at all.Some of the code below...

float values of array are not assigned during a for loop

I want to convert a bunch of uint16_t values from an ADC into floating point voltages. For this I use a for loop to loop through the uint16_t array and write the values to a float array. But the float array remains 0 as if no assignment is ever made....

Fast Timer Interrupt Distrupts My Program

I need to achieve fast interrupts because I'm making integration from accelerometer and gyroscope datas in my code. And when I set a timer interrupt frequency to 2.5ms code get stuck. But when I increase timer frequency to 25ms it works just fine. ...

[STM32F3] HSE crystal selection, confused by AN2867

I'm trying to select a suitable HSE and size the capacitors + resistor for it following the procedures laid out in AN2867, but I can only reach a "not compatible" result even with the example values used in there (the different stages are done for di...

STM32L412 RAM Issue

Hello Folks,Im working on STM32l412kb uc (40 kb RAM Size) .My code uses 32kb of data still we have 8KB RAM.But there is one issue with our results i.e stack size overflow we dont get desired output that is only due to stack size overflow.We also o...

STM32F072RB discovery board The STM32 in slave mode is to be used to read sensor data at every 2 second interval by an ESP8266 master through I2C. I am using the HAL library for this.

The I2C interrupts were enabled and HAL_I2C_Slave_Receive_IT() and HAL_I2C_Slave_Transmit_IT() functions were called. The slave can receive and transmit the data only once and then it pulls the SCL line low disabling further communications. I have tr...

STM32L051 PA12 not set and always 0 (RTS problem). How can I use PA12? I'm already found that PIN always set as RTS and read errata for my MCU that states "Configure as alternate function after setting the UE and RE bits." How to use PA12 as GPIO?
