Resolved! How do I select different output voltages from the STUSB4500 without using a microcontroller?
I want to use a STUSB4500LBJR for USB-C power delivery. On the datasheet stands that connecting the I2C lines is optional and in another datasheed of the STUSB4500 stands that I don't have to use a microcontroller. But I cannot find information about...
Reading from L9663 PSI5 Transceiver
Hello,I am using L9663 PSI5 transceiver for the development of a steering drive project. I have a doubt regarding the SPI communication. If I want to read a register content will I be able to get it in the same MISO data?For example, I am sending a 3...

BlueNRG I2C with DMA using LL - no STOP condition - why?
For some reason I need to rewrite I2C functions from HAL to LL. As I aim to achieve good power consumption results, I decided to use DMA and IT in order to save as much resources as I can. There is all ok with writing data (HAL1 and LL1 pictures) but...
Which BOM to use for SMPS for BlueNRG-LP: the one from Reference Manual (RM0479 Rev1) or from STEVAL-IDB011V2 - Rev 1 ?
Hi everyone,I'm confused in regars of BOM for SMPS for BlueNRG-LP. In the Reference Manual we can see the following recommandation: and in the document for the evaluation board there is another solution: Would it be possible to get an answer if both...
