Hi,Hope this is a simple question.I use this device: STM32H753ZIT6I don't intend to use USB so looked in the datasheet and found the belowDoes that mean I can safely connect VDD33USB to GND?Thank you.
NVIC_Type members are different for CMSIS 5.90 to CMSIS 6.0.0. Member IP renamed to IPR.STM32F1 SPL needs to be modified to be compatible with CMSIS 6.0.0.
Hi There,I'm trying to set the clock configuration of an STM32L4S5 and have spotted some ambiguities in the reference manual concerning the maximum input frequency to the PLL:RM0432 6.4.4 says the following in the context of choosing the M value when...
Here comes another query about the status of a HUB device for the USB Host library. I have been working with the driver from herehttps://github.com/moribr/STM32F4HUB/blob/master/Project/Middlewares/ST/STM32_USB_Host_Library/Class/HUB/usbh_hub.cand ha...
I'm using an STM32F429ZIT6 chip.In my program, the BUSY bit within I2C->CR2 becomes set and never returns to clear. I have verified on a scope that both the SDA and SCL lines remain high during this time and yet the bit remains set. The SR1 register ...
I'm using the cube for generating code for IARthere is an ADC with to a DMA the MX_ADC_Init() fail, can't tell why the ADC configuration: the DMA configuration: when i run the code, the fail point is: i have checked that the DMA is initiate first ...
Spoiler Hi, I have a question about the size of the flash of STM32G0J6. When i use STM32 cube programmer - CLI i saw that the size of the flash of the STM32G0J6 is 64Kb. I try to write everywhere in this memory it works. The datasheet say that the S...
Hi,I am trying to read Total 3 ADC Channel using DMA, Successfully completed and tested in Debug Mode. I had connected OLED to display the same in while loop. It works normally without DMA Enabled. But when DMA is enabled, Display is not working and ...
i was doing a project and while i trying interrupt in a normal program its working fine , but when inothe rprogram while im running some transmit function in while loop , the interrupt is not recieving and if i commenting that transmit function the i...
I have implemented a hallinterface (tim 1), to update my pwm timer (tim 8). But the delay i set is rather fluctuating.Disabling interrupt inside of the tim 1 interrupt did not help. And i think, outside of the interrupt it should not matter, since th...
