Other Parts Discussed in Thread: TMS320F28033
Hello everyone,
We have a design with two DSP processors (both TMS320F28033). Initially these devices will be programmed with JTAG but later when on the field the code may be updated remotely through ZigBee. This means both of the DSP codes will need to be updated. One DSP will be exchanging information (transmit and receive) with the ZigBee continuously - status updates, control parameters etc. The other DSP will only receive code updates from the ZigBee.
I was thinking of connecting the SCIRXDA pins of both DSPs together and to the ZigBee. This will be used to receive code from the ZigBee. Is there a problem with connecting SCIRXDA pins of two DSPs together? The SCITXDA of one DSP chip will be connected to the ZigBee for transmitting status updates.
Besides this, the DSPs communicate with each other through I2C with SDAA and SCLA pins connected together. These are very slow and occasional data transfers. I hope this is possible? Connecting these pins together and configuring one as a master and the other as a slave?
Thanks in advance.
