1.1 Reading and Writing Sensor Register
This example script:
#!/bin/sh
cmv_reg() {
addr=$(( 0x60000000 + ($1 * 4) ))
[ $# -gt 1 ] && devmem $addr 32 $2
devmem $addr 32
}
#change the registers 69/98/102/107/108/112 and 124
cmv_reg 69 2
cmv_reg 98 39705
cmv_reg 102 8312
cmv_reg 107 9814
cmv_reg 108 12381
cmv_reg 112 5
cmv_reg 124 15
#read the register 127
cmv_reg 127
basically the registers get mapped to 32bit spaces starting at a specific memory address (0x60000000 in this case), reading from that memory will show the register, writing to that memory will change it
so register '0' is at 0x60000000, register '1' at 0x60000004 ...
