Discussion - Hardware / Start problem on V2DIP1-32
« on: January 13, 2023, 10:52:27 AM »
He,
we develop a little firmware on the V2DIP1-32 which retrieve the data from an HID device and forward to a UART bus.
We use a custom firmware because, we need to send a periodic frame on the uart bus (10ms).
As you can see in the attachment files, sometimes, the V2DIP1-32 start with a degraded performance. To track the problem, we created a "alive" thread with the high priority which toggle a gpio pin every 10ms.
When the V2DIP1-32 starts with a low performance, the "alive" thread toggle the pin every 20ms and the uart frame is sent every 120ms!
Any suggestion about this performance degradation?
