Interfacing Nova SDS011 with LPC1768
Nova SDS011 is Particle matter sensor which measures in PM2.5 and 10 and gives an output in through UART.' Please find the attached packet format of Nova SDS011.
The no.of bytes is 10 (i.e 0 to 9 bytes transmission). I need to read only 4 bytes (i.e Byte 2 to Byte 5).
Am able read only the data for the first time when i reset the Board. After that not able display or read the sensor data and also nothing is displayed through terminal ( UART). Independent code without sensor (UART ECO) is working fine. Issues is with sensor interfacing.
Below is the code for reference. /media/uploads/Venkat_Smet/code.txt
