Tips needed for designing PID controller and testing to monitor LED temperature Hardware:STM32L4 Library: HAL DSP library (I am ok to manually design and bypass DSP lib)

Hi all,I am trying to design PID controller to monitor LED temperature Control Variable: Parameter that adjust the LED brightnessProcess variable: LED temperature (measuring it with sensor) I am looking for some tips to tune my PID parameters as well...

STM32F7 Triangle-wave generation

I am trying to control the amplitude of a triangle wave, while the frequency of the waveform should always be 1kHz. Is this possible to do?The reference manual says that I can control the amplitude of the signal using the register DAC-> DHRx. Further...

How much can I overclock the STM32F303xx MCUs when powered by 3.3v and running at room temperature?

I'm using the STM32F303xx MCU in an application with a 24.576MHz crystal. The MCU is powered from 3.3v. I am currently clocking the processor at 3x 24.576MHZ, or just slightly under 74MHz. I realize this is above the rated maximum processor clock ...

I have trouble writing to flash using HAL_FLASH_Program in case of FLASH_TYPEPROGRAM_DOUBLEWORD option.

I have the code working fine with the 1byte, 2bytes and 4bytes programming, reading and writing. But when I use the 8Bytes (double - word), It is always trapped in a hard fault handler. Any help?

MCO pin showing 24 MHz instead of 48 MHz while debugging

I use the MCO pin to test my clock configuration on a STM32F072RBT6 board. While I'm debugging with a ST-Link/V2 adapter the MCO output shows 24 MHz instead of the expected 48 MHz.Using the exact same software (no changes in clock configuration) and ...

entropy source failed

Hi,Im using the STM32F746NG Discovery Kit MCU. Im getting following error when trying to make a HTTPS connection:mbed_tls ctr_drbg entropy source failed.Although I enabled the RNG and CRYP Module I put following macros into my mbed config.h:#define M...

Over the Air Firmware suggestions

We are developing a product and are stuck at Firmware over the air updates. It seems like we will need a system that meets the following requirements:From a firmware perspective, the platform should support delta updates so the entire firmware packag...

STM32F7 interface to DS3231MZ+

Hi,We are trying to interface STM32F76 custom board to DS3231MZ+ RTC chip ,we are able to set and retrieve time using I2C and it is incrementing properly as long as board is powered up. But Time and date are reset to 0:0 and year 2000 after board...

STM32L011F4U3TR part received with the marking 'L143', which is different from marking 'L011F' in the datasheet. Please help check whether the stock is correct? Thanks, Siddu
