Hello,In our application, we need the M7 of the STM32H755 to boot first, and after it initializes to allow the M4 to boot.We set the option bytes per CubeProgrammer such that BCM7 is enabled (checked) and BCM4 is disabled (unchecked). We also set a ...
What will be the total output current sunk by sum of all I/Os and control pins and Total output current sourced by sum of all I/Os supplied by VDDIO2 of STM32F103RBT6?
It is vital to use language and terms with great care and precision in technical writing. Whenever you don't, you create confusion. Newcomers often make the mistake of conflating the terms "crystal", and "oscillator". For example, see @Andrew_Neil ...
I believe there is an error in the STM32G4 Series Reference Manual regarding the width of TIMx_ARR for timers 3 and 4.The reference manual shows a width of 20 bits for TIMx_ARR for timers 3 and 4, below.However, both TIM3 and TIM4 are 16-bit timers, ...
Hi,I'm somewhat new to STM32. I need to use DMA to collect data from a tempreture sensor over I2C.My sensor is an Adafruit MCP 9600 and I'm using a Nucleo F446RE board. Following is the code I use. Can someone help as I've been stuck here for days wi...
Hi... We are planning to use STM32H503KB (32 pin package) in our application. The MCU VDD is supplied from either of the two sources:1. With power supply (5V)2. With 3V cellOur need is to bring the MCU to standby mode when the supply is provided from...
Is the ADC available in low power run and sleep mode for the STM32G070RB?I am trying to monitor 4 ADC channels continuously with a power budget of under 100uA. I would use the analog watchdog to wake the processor in the event of tripping the high or...
Heyho,and one more problem with my custom board with a STM32H733ZGT6 (LQFP-144, almost same as H723 on Nucleo).I'm using TIM5 for input capture, with CH1 (GPIO A0) and ETR (A4) as external clock input.The setup code is the same as on H723-Nucleo and ...
STM32F107RCT6 has 64K Bytes SRAM in total , i use just 26K Bytes, and heap still available, but it overflows, i get confused. if i just change Heap_4 to Heap_5, my code can compile successfully, but it doesn't work. how to solve this problem?
Hi. I am using STM32L010C6Tx. I want my microprocessor to sleep for 10 seconds after processing. I want to use Sleep Mode. I don't have any interrupt pins. I want it to wake up after 10 seconds. How can I do?
