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...
STM32F050C4T6A I want to use as a drop in replacement since I cannot find stock in the STM32F030C8T6 When I installed it in my board I use two I2C ports and they both work but the manual says there is only 1 I2C port. Am I ok to use this chip going f...
Hi,I am trying to perform continuous ADC conversions from a microphone using DMA, save that data to a large buffer, and then transmit that data using Uart (DMA). I have successfully setup the ADC to perform the DMA conversions along with saving them...
Hi, I have the problem that I get an endless slave Clockstretching.STM32F072 I2C configured with CubeMX, Primary slave adress $32If I fire a Tx frame from a master with for example:HAL_I2C_Master_Transmit(&hi2c1, 0x64, buf, 1, HAL_MAX_DELAY);The cloc...
Hello,I am using GCC and eclipse CDT. I need to execute an external interrupt very fast (every 4µs). There is not a lot to do in there but I use about 2.5µs of time in the interrupthandler. I tryied to put the handler in to ram wich gave me the reloc...
We switch several times the µC into Standby Mode and the current is as described in the specification.But sometimes over the Vdda Pin the current is 1mA. We switch adc/dac vrefint etc off. No BOR in use.We checked each Ports, but the current is comi...
Hi, i got a fan failure project . For that i need to select 2 adc channels in DMA mode for rms calculation , and 2 digital input for my powerfactor reading . here i am using AC (230Vac) and DC (5v) supply both .I select two timers with 100khz in...
Hello everyone! I am trying to debug some code but there are some flags in flash that keep getting set when I exit debug and it enters run mode (or when I power up the sensor. Basically, anytime it gets a chance to run before I can get it in debug ...
