Posted on May 17, 2011 at 12:07hi, you cannot directly route PCA#CLK to an output. but you can use the TCM# to i.e. toggle a pin according to PCA#CLK. if you really need a ''fast'' clock-output, you can route the _ale-signal to an output-pin in the ...
Posted on May 17, 2011 at 12:06hi, - the obj-file contains all firmware, AND the configuration data for the PSD. - the hex-files contain the firmware (for the mcu) - this is what is written to the flash memory to determine the size of the firmware f...
Posted on May 17, 2011 at 12:06hi, rs485 is not a protocol, but a ''physical layer''. you should handle the rs485 like a ''normal'' uart (rs232) from the 8051. (see UART-section in the datasheet.) the rs232-rs485-conversion has to take place outside...
Posted on May 17, 2011 at 12:06hi, no, there is no ''start condition''. but make sure to configure/trigger or disable the watchdog. if you want to know if the microcontroller is running, configure 1 pin as output and toggle it in an endless loop, an...
Posted on May 17, 2011 at 12:06hi, this is simple: - set the adress-ranges for the flash-sectors/sram in PSDflash. (i.e. for SRAM: 0x000 ... 0x1FFF) - read SRAM: MOV DPTR,#0000h ;read 1st byte in SRAM MOV A,@DPTR MOV DPTR,#1234h ;read byte at addre...
