I am testing Examples/OPAMP/OPAMP_PGA/ in G4 package code, only to find the gain is not consistent as showed below:The OPAMP input values are 0.01,0.03, ..., 0.15, and gain is 16.However, I measured output at ADC side, the gain drops significant as i...
Hello again,I recently checked the time the STM32F7 (192MHz) needs to copy one 32bit buffer to another one, and I'm a little shocked about how long that takes.(Maybe I expect too much, coming from 8bit µCs with 20MHz, an STM32 still feels like a raci...
I've been sampling some signals using this ADC, embedded in the board NUCLEO-F767ZI but when it reaches the 113th sample, samples are taken wrongly, as I have plotted the memory and the signal shown doesn't correspond the one I am generating. Find my...
Hello I have an application where it would be usefull to have a pin configured as an open drain output but at the same time to detect a falling edge on that pin usirn EXTI. In the refference manual RM0091 there in Figure 18 (Output configuration) I h...
Hello, I’m working on a project using the stm32l562E-DK. The project is based on (mainline) TFM with a secure and nonsecure application, and bootloader. I’ve modified the TFM sector definitions to change the sizes of the sectors. The bootloader and s...
Hi EveryoneI have a very strange issue in the SPI of my STM32H745.Consider following information0) No Master present on the Bus1) SPI5 is configured in slave.2) No interrupts, no DMA just polling3) Following is the initialization code (FIFO is set to...
Can anyone share related docs
Iam using stm32 IAR workbench 8.20.Iam trying to run scanf. but scanf isn't reading first character of any data type. If enter 1234 through keyboard then it will print only 234.does anyone know how to resolve this issue???
Hi Sir, we need to uncompress the ECC public key. Now we are using Crypto_v4.0.1 LIB. We could use it on comx_aead&hash&ecdh API. Please inform us how to use the ECC. We need the uncompressed X point Public key to Y point.
I have attached the complete log here..I am trying to use the External mode with Nucle 412 board. But with the above said error.., I am unable to connect to the board at all.., I initially reported to MATLAB, but they closed the issue stating that i...
