Hello, i ordered a STM32F429ZGT6.Now i try to identify the revision of the chip i got.The marking on the package seems to have changed - there is no ARM Logo anymore.And where the revison was printed in the past there is now a QR-Code.Is 340 the date...
Hello, I am using a STM32F334 for a project where I am reading several analog channels, specifically connected to thermistors. I am using DMA to read the analog channels and also sending this data out on UART via DMA. I am seeing some weird jumps in...
Hi,I have an STM32H747IGT6 that I wish to:Continuously sample 4096 ADC samplesTransfer each sample from the peripheral to memory using DMATrigger an interrupt at the end of the conversionsAfter the CPU operates on the stored data, restart the process...
I work with a 64 bit linux and a stm32f411ceu microcontroller.Unfortunately there is no detection under linux from the uart port. Are there experiences or sources?
I was unable to configure ADC1 to measure a "4 channel sequence" and then generate an interrupt.I am using the injected result registers to read the values in the ISR.Adc_Value[0]= ADC1->JDR1;Adc_Value[1]= ADC1->JDR2;Adc_Value[2]= ADC1->JDR3;Adc_Valu...
Hello,I would like to know whether I understood the application note about the Vcap pins correctly. If there are 3 Vcap pins on the package, then 2 capacitors should be placed and one has to be connected to another. I'm not sure about this connection...
Hello guys,In some of the products we developed with STM32F429, we received the write-protected error I mentioned in the image. I know how to turn off write protection, but I can't figure out how it activates independently. However, there are also ma...
Heyho,first of all, I know this is a Microchip product, but their forum is rather dead.And I have seen some people here using the KSZ8863RLL. So please bear with me... I'm currently working on a big and complex PCB including the "dual PHY" KSZ8863RLL...
On a STM32H745ZI-Q - Board I want to create periodical 4-byte SPI transfers triggered by a timer. So far I got this working the following way:TIM triggers DMADMA initiates the SPI transfer.However, the SPI transfer timing (CS low) has a high jitter ...
HI all, I am building a system to control my battery charger.When I power up the system from the DC power supply it work perfectly.But when I power up this with AC power supply it gives below error. What can be the possible error?
