Other Parts Discussed in Thread: MSP430F5438A
Introduction
Hello, I developed a wireless device, which continuously transmit bulk data.
- MCU : MSP430F5438A
- BT : CC2564B (PAN1326B)
- Throughput : 400 kbps
And I wanted for MCU in this device to do data processing before bulky data transmission,
By using Bluetooth stack code, however, UART protocol was an too much burden to compute additional data processing,
So I wanted to design for UART data transmission by using DMA control.
Problem - no DMA trigger assignment option about UCA3TXIFG
From DMA in MSP430F5438A , I can only select UC- A0, A1, B0, or B1 interrupt flag (page 50 in datasheet),
but in stack code, MCU-Bluetooth UART connection was UCA3, so I cannot send UART data by using DMA.
How can I transmit data by using DMA?
