BOM- UHF /sensors pir motion
Hi mga sir,
this is my application ,
two station ( a & b)
scenario, one lane road. it will be half duplex passage way.
How i can set my UHF?

i just want to know anu po yun mga gagalawin ko na code sa given sa cd

gpio - yes , to set the pins that is input and output
main- to set the uhf if it is recieving and transmitting/ this where ill put my if else code ?
spi-? no idea
timer- i think i dont need it, ill just use delay.
variable- declaring variables
ata5812- mukang di gagalawin eto, kasi setup ng tranmitting between the zilog and the atmel rf mcu ng uhf
