MDDS30 SerialPacketized Error

[al3c00]

Hi
I'm trying to use multiple MDDS30 Rev 1.3 with Serial Packetized Mode on a pcb. However i can't even get to run one unit (doesn't matter if i use your example code or write my own). I send the dummy byte 0x80, then the error lights stop flashing 2x. When i want to use the control funtion from the example code the lights start blinking again. The switches are 11100000. Was there a change in Rev 1.3 that isn't mentionend in the user manual?

Thanks in advance

Found the cause of the troubles: The size of the checksum is only one byte but Command Byte 255 + Header Byte 0x55(85) would be 340 which should be at least a uint16_t. This leads to buffer overflow and a corrupt/false checksum...is there anyway to evade this?

Hi. Sorry for the late reply. For prompt response, you may contact [email protected] directly in the future.

Regarding the checksum of MDDS30 packetized serial mode, it only takes the LSB of the checksum.

Thanks.
