Dear experts, we like to develop new VFD spindle motor controller, with V/Hz open loop control. I am searching for a modern reference design for 220V applications, based on the STSPIN32G4. But I could only find designed for BLDC, focused on FOC, but ...

Dear support team,is there Reference schematic, register description or a Eval board for the FDA2100 Class-D amplifier available? The datasheet does not contain these information. Or is an NDA required?Also: the HFDA801A seem currently not stocked at...

Dear experts. we plan to use a STM32MP157, where the A7 core should have 512MB DDR RAM, and theM4 core 16 MB. What options exists, to give the M4 core that 16 MB of RAM?From the DS, i understand that the DDR RAM of the A7 is not accessible for the M...

I have to design a system, where a STM32MP157, with its embedded Cortex M4, communicate with other clients over a high-speed serial connection. There should be a 10 : 1 serializer for the MOSI line, and a 1 : 10 deserializer for the MISO line (from t...

Dear all,ST brought a new feature to the STM32H7A/B and some L4+ MCUs, the "parallel synchronous slave interface (PSSI)". We would like to use this for a fast host-to-host communication. But this interface seem so new, we could only find register de...

Hi PatrickF,thank you for the answer. I know, that this specific use is not guaranteed and not tested from ST. I just wanted to hear, if there are some obvious no-go's I had not seen before, before we invest in buying boards and time. Your answer not...

Dear Amel,To answer your question: when I was writing host-to-host, I was thinking about the function of the chip, not the interface mode. Of course, there will be a master and slaves, as in the example with the 2 NUCLEO-H7A3ZI-Q boards. About the pi...

To answer my own question: I have found a great example under https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/NUCLEO-H7A3ZI-Q/Examples/PSSI/PSSI_Transmit_Receive_DMAThe only question open now for me: In the above example, only ...

Dear Jack,thanks for the answer. If I would have enough time and no pressure to have a solution in a somehow short time, I would of course do, what you suggest. But unfortunately, I am not in that position. I must build a product with USBTMC working,...

Posted on June 13, 2018 at 04:08Dear Jan,thanks for your fast response and the patience to answer my questions. After seeing the limitations, i will go the route with an FPGA. The hint with the DCMI was good, but actually not within my requirements....

Dear Experts, can I use the DCMI on the STM32MP15x, with the Cortex M4, for an asyncron connected non-camera source?

parallel synchronous slave interface (PSSI) Host-to-Host app-note or example.
