Micro-ISP
Device Programming Guide
The Micro-ISP Programmer is now ready to program a target device.
In the following example we have chosen to program an Atmel AT90S1200 microcontroller
located on the user target system.
1 From Meridian select <Options> <Create Library Info>
This operation interrogates the target programmer and generates a 'notepad' document
which details information about your programmer and generates a list of devices supported
by the programmer. From the list you can see which 'TARGET ISP' devices can be
programmed with the Micro-ISP. i.e. only devices listed as 'yes' or LNR' are supported.
2 To select the target device click on the
<Device menu>
Chose <Select>, Chose <AT90S>, Chose <Target (ISP)> and finally
click on the target device, in our example <AT90S1200ISP>.
3 From the< Device menu> select<Information>
This will give you a description of the target device.
4 Setting of target write times
(LV programmers only)
The write time of the FLASH and EEPROM varies with target
voltage. Meridian defaults to the correct settings for +5V. If your
target system is powered from less than 5V it may be necessary
to change the write time.
IV User Manual V2.03
Series
To alter the write time settings select
<Options> <SPI Program Options>
Enter the recommended 'Write Time'
- for the selected device from the
tables overleaf
Enter the required 'EE Write Time'.
This time is automatically updated to
be the same as the 'FLASH write time'
for all devices except the ATmega
family. Click <OK>.
