how to convert received uint8_t array to string in stm32 ?
I am receiving data from UART in uint8_t array.I want to convert array to string to work on it:if (Received Data=="Reset") { resetFunc(); }if (Received Data.substring(0,8)=="ABCDASD"){ Do something }if (Received Data.substring(4,8)=="ABC1234"){ int...
Is it possible to separate MAC and PHY configuration in HAL driver?
I'm currently working on custom board that uses a stm32f2xx chip and PHY chip that is different than the one in dev/nucleo boards. I noticed that I need to change HAL code to get this combination working as the MAC and PHY initialization is combined ...
Two channels from the same ADC
Hello, I have a custom STM32F439VITx based board, with two analog sources wired to PC0 (ADC1_IN10) and PC1 (ADC1_IN11). The sources need to be read infrequently, on the order of every five to ten seconds, and independently of each other (so sometimes...

HAL_ADC_GetValue giving wrong values
I'm trying to use HAL_ADC_GetValue to get the ADC value from an STM32L082 attached to a battery giving 3.7V. My goal is to use the ADC value to estimate the battery percentage so I need the ADC value when the battery is full and when it's mostly empt...
Why my chart not displayed?
Could you tell me what I'm doing wrong?I want to draw a sinusoidal chart. But for some reason, it is not displayed in the window of "SWV Data Trace Timeline Graph".PS - A "cleanSignal" it is a global variable.

IWDG watchdog timeout even refresh it
I have a customized bootloader and a main application.Both of them init the wathcdog, and refresh it. But when my bootloader jump to application, the refresh of watchdog from application sometime does not work. The watchdog still timeout.But if run t...
High accurate sine wave using STM32H7
Hello,Is it possible to generate high accuracy in terms of the frequency sine wave using STM32?My goal is to generate a sine wave using STM32 whose frequency varies from 5KHz to 20KHz insteps of 0.1Hz with a delay of 1 sec is it possible to use STM3...
