Even if the FAT_SHELL.C sample works flawlessly (the SD card has two 2GB FAT16 partitions) the function "sspec_automount(SSPEC_MOUNT_ANY, ..." returns "2" at the beginning of the "main" in my project. The problem arises exactly here: https://github.com/digidotcom/DCRabbit_10/blob/master/Lib/Rabbit4000/SDflash/SDFLASH.LIB#L993 https://github.com/digidotcom/DCRabbit_10/blob/master/Lib/Rabbit400...

Using DC 10.72A/D, with an RCM6750, when the ARP Table size is increased from 64 to 128, the executable bin file size is increased by 52k. Does that seems right? That seems way out of proportion to me. The reason I increased the ARP table is because of the way the R3k modules work. Every device on the network that they see, they add to the ARP table, printers, computers, oscilloscopes, mobile ph...

I'm trying to test the analog output on new board BL4S200. The jumpers on the board are by default as described in the sample program. The board is powered with 12V DC (J5-pins 1,3). The only connections are the 2 connectors on J5 and J12. I bought the connectors with the 1 ft. cables pre made from Mouser. The Analog Inputs work fine ( used sample prg: adc_rd_se_unipolar.c ). ...

I downloaded v10.72D of DC and installed it. In the previous version of 10.72 I have (I don't know what letter version it is),I am using function I2C_initClk() found in I2C_HW.LIB to switch between a 200kHz clock and a 400kHz clock. But thatfunction is not there in v10.72D. Is there another mechanism provided to do the same thing that I'm not seeing? Steve

I tried using the Windows RFU to program an RCM6750 and there is no longer a button on the main window to tell it to start programming. The image file is set, the processor type selected, the port to use is selected, the communications options menu is configured, file locations are set. Everything is as it should be, but I have no way to launch the programming. Very weird. Any ideas? Steve ...

I have an RCM3900 module that has a TCP connection with a host. The module is receiving TCP packets at about a 1-second rate. So everything is humming along with the host sending TCP packets requesting status info, and module responds with the data.  After a some time, minutes to hours, of running, the module issues 2-gratuitous ARP packets, about a second apart. And upon receiving the next TCP ...

I have an app for the RCM2200. There is clearly a battery position marked on the upper surface (3 pins, 25mm spacing). I will need battery backup and it would be easy to add it to the CORE. Any idea which battery fits? I found a cr2032 mfr that looks close. Thanks in advance, David
