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,while using this mcu 16bit adc a strange thing happens.the adc signal is test under a sinusoid signal(0.5Hz from a signal generator), and as shown in the figure at certain level adc keeps unchanged, after leaving this level then the signal incr...
The code I wrote for the B-L072Z-LRWAN1 is supposed to count pulses on a falling-edge external interrupt pin. The pulse source is an Arduino which toggles its GPIO on and off every 5ms, for a 10ms pulse period. after 6 seconds, the B-L072Z-LRWAN1 tra...
We have designed a boards, main board has STM32H742VGT6 and it is connected to Microchip PHY IC KSZ8091RNBCA in RMII Mode, Onboard Clock 25Mhz for PHY) we have tried basic configuration such as enabled ETH, LWIP Stack.we are using STM32CubeIDE 1.13...
I am using an STM32G473MEY3 MCU. I am looking in the reference manual in the FLASH section, but I am not sure if this is a cateogry 2, cateogry 3, or category 4 device. I am thinking category 3. Any ideas?
I am trying to use the LSI as the clock source on the STM32 G0B1KEU6. It doesn't work, and as soon as I select the LSI in the MUX on the clock tree, my code stops working. To ensure there are no other sources of error, I used the exact same code but ...
Hy,I have tried to resample a 16bit/8kHz audio signal to 16kHz and 48kHz.Conversion works, but the audio is noisy. I am tested it on development board STM32H747 CM7 core.I have tried libraries: SRC236_CM7_GCC.a and SRC236HQ_CM7_GCC.a without quality ...
I am looking to create a USB to I2S/TDM interface.I generated a Full Speed USB AUDIO DEVICE skeleton from CUBE MX.I made some changes and I have working code in FS.I generated a skeleton in High Speed. I made the same changes and it doesn't work. T...
Hi all,Total newbie here.I am seeing this error in Windows 11 Device Manager: "Device Descriptor Request Failed", when I plug the Bluepill to a PC using Bluepill's onboard micro-USB PortAlthough the Bluepill looks like it is running OK with the previ...
Hello, I am attempting to have a two stm32 nucleo boards communicate by sending and receiving can messages. My goal is to have the PA5 LED of the STM32 f446re blink when a can message is received. I know that the canbus must be configured to classic...
The attached code configures UART communication to wake up a microcontroller in sleep mode as soon as a frame is received. In sleep mode, the micro waits for data on the UART interface, and when a UART frame is detected, it automatically wakes up t...
