Some of Rabbit cores (eg RCM3100) have an "hardware" PWM output. The sample you've posted is (most probably) for using this output. If you want to make your...
A Li-Ion cell (with the built in safety circuit) can be safely charged without monitoring temperature IF YOU DO IT SLOW. The LTC-4053-4.2 is designed for...

Lead Acid batteries are certainly less "fussy" about charging and discharging. In fact, theoretically they can be floated indefinitely at about 2.15 to 2.2...

Hi All, I have problem with Data hold time problem. I am using Auxiliar I/O bus interface with A/D (AD7938) from analog. From the I/O access time spec of...
... Add a 74HCT245 to the data bus. That will add a delay. The problem is you don't have a direction line from the rabbit modules. I solve that by using one of...
Hello everybody, I am trying to interface an iridium satellite phone 9522 with the Rabbit microcontroller. I am using 3 wire RS232 interface. The problem is...
I interfaced a Rabbit to a Iridium modem about 5 years ago for my previous employer. From memory it had flow control on my default. Are you positive you are...
Nathan, You are right that the flow control is "on" as a default. I disabled it with AT&D0 and AT&K0 commands. I saved that profile to the memory so that...
Are you sure you're sending the commands and looking for the response OK? If your not sure you could connect Hyperterminal up to the Rabbit (crossing over TX...
I had this problem also some time ago with Iridium. It is not sufficient to simply loop back the control signals as the Iridium will not assert CTS until it...
